From what I've read, people recommend these from MSY (though they're a little more expensive)
- CoolerMaster CAC-T05 ($109) [apparently the cheaper CMs have cheap PSUs]
- Antec NSK____ ($119 for 380W, $128 for 430W)

Personally think you could probably get away with a cheaper PSU, but there's quite a few people who wouldn't even think about it, so you decide...
